Hello friends, Today share my experience on Ambrane Power Bank. I buy this Power Bank some months ago, after few days its makes many problem. Its power automatically drain whih out use. Its battery backup really poor maximum its battery backup 2 hour and quality drain. The power bank take huge charging time. Its body material is made by poor quality so use very carefully. Its not a reraible product. It’s looking not good, its design is old fashion. My view of point this product market value is not perfect against its performance and reliability.
